Discuss the role environment plays on phenotypes.
In recent years, scientists have begun to research how our environment can impact our phenotypes. In this outcome, we’ll learn about a few different ways our environment can impact us.
What You’ll Learn to Do
- Explain how epistasis impacts trait expression.
- Describe polygenic inheritance and how to recognize it.
- Describe continuous variation and how to recognize it.
- Identify gene-environment interaction and how this impacts trait expression.
- Explain pleiotropy and its impact on traits in a population.
The learning activities for this section include the following:
- Reading: Epistasis
- Reading: Polygenic Inheritance and Environmental Effects
- Reading: Effect of the Environment
- Reading: Pleiotropy and Human Disorders
- Self Check: Genetics and the Environment
